An additional experiment has been performed to evaluate the added value of LF images in comparison with single-view images for face recognition. This considers the comparison between four LF-based face recognition methods including LFLBP [1]}, HOG+HDG [2]}, VGG-16 + LSTM [3]}, and the proposed ResNet-50 + Capsule, and their corresponding single-view versions, including LBP [4]}, HOG [5]}, VGG-16 [6]}, and ResNet-50 [7]}, applied to the central SA image. The results presented in Table REF  clearly demonstrate the superiority of the LF-based methods over their corresponding single-view baselines for the four subject-dependent test protocols, thus highlighting the added value of LF images for face recognition.
